To all whom it may] concern.'

Be it known that I, HAROLD B. CRANsHaw, a citizen of the United Statesof America, and resident of Boston, in the county of Suffolk and Stateof Massachusetts, have invented new and useful Improvements inReceptacles, of which the` following 1s a spec1- cation. 4

This invention relates to paper receptacles and more particularly tosputum cups of the type intended to be destroyed after use.

Tn articles of this character 1t is essential that the receptacles becovered and considu lerable diiiiculty hasv been experlenced 1nproducing a satisfactory covering. Tt is the object of the presentinventlon to provide a covered receptacle of the character referred tohaving a pivotal cover which can be readily hinged to the cup, which maybe hinged to the cover with or wlthout tne use of metallic or otherauxiliary attachingmeans, which will not become detached from the cupunder ordinary conditions of p usage even when employing no auxiliaryattachment means, and to provide a covered receptacle which may beformed ofy two parts, one part being adapted to form the cup and theother part the cover, andeach part being adapted to be formed by asingle stamping operation.

The preferred embodiments of my invention are illustrated intheaccompanying drawings, in which- Figure l is a side elevation of thereceptacle showing the cover slightly raised;

Fig. 2 is a rear elevation of the receptacle;

Fig. 3 is a plan of the cup is formed;

Fig. 4, is a plan view of the -receptacle showing one form of metallicauxiliary fastener; and

Fig. 5 is a side elevation of Flg. 4.

The embodiments of my invention 1llus4 the blank from which trated inthe drawings each comprises a cu 1 C and a cover C', the cup C having atab projecting through a slot S in the cover C. The cup C is preferablyformed from a blank such as shown in Fig. 3, the blank being foldedalong the dash lines to form the cup in a manner which will be readilyunderstood. The portion 1 constitutes the bottom of the box, 2 therear-side, 4 the left side, 6 the front side, 8 the right side; theportions 3 and 9 are folded inwardly along Specification of LettersPatent.

This application led February the inside of the rear side 2; theportions 5 and 7 are folded inwardly along the inside of the forwardside 6; and the projections 10, 11, 12 and 13 are folded inwardly andinterlocked together as shown.

The portions 10, l1, 12 and 13 when thus folded and interlocked, form acontinuous flange which serves to prevent the escape of the contentsofthe cup, should the latter be accidentally turned on its side orcompletely over-turned.

he cover Cconsists of a flat sheet of material and preferably extendssomewhat over the edges of the cup. Both the cu and the cover are`preferably composed o stili;` paper, the cover being somewhat moreinflexible than the cup so as not easily to become warped or distorted.

In my improved means for pivotally at.

taching the cover to the cup the tab is preferably formed on the cup andthe slot in the cover and the tab is preferably formed as an integralpart of the cup. As illustrated in Fig. 3 the tab is struck-up from theportion of the cup blank with its base Patented Feb. 1, 1921.

extending along the line 14 which constitutes the upper edge of the rearside of the box when the blank is folded. Thus tletop normally extendsfrom the edge of the cup in alinement with the rear side 2 as shown inFigs. 1 and 5. However, the tab is sufficiently flexible to permit itsbeing bent backwardly when the cover C is raised.

A characteristic feature of my invention is that the tab T is wider atits top than at its base and that the slot S is narrower than the top ofthe tab, and these relative dimensions are preferably secured by formingthe tab in the sha e of a keystone as shown most clearly in Ilfig. 3. Inthe embodiments illustrated the Width of the slot in the cover issubstantially equal to or slightly greater than the width of the tab atits base so that the cover fits snugly around thevtab and this is thepreferred construction.

In inserting the tab-through the slot the tab is Hexed into such formthat it is no wider than the slot, as for example by squeezing inwardlyon the opposite ends of the tab, and in order to facilitate theinsertion the cover may also be flexed on one or both sides of the slotso as to widen the slot and provide a larger opening for theulexed tab.After the tab is inserted through the slot the tab is permitted tostraighten out and when the slot is of substantially the same width asthe base of the tab the cover is held close to the cup. Moreover, thereis no tendency for the cover to pull o the tab Aunless the tab is flexedin some such manner as above referred tot While the above descrlbedconstruction 1s wholly satisfactory for most purposes an auxiliaryfastenin means is desirable under certain severe con itions of usage. Itherefore provide a clip characterized in that it fits over the edge ofthe cover and extends through the tab either above orbelow the cover oron both sides 5f the cover. In Figs.

4 and 5 I have illustrated an embodiment of auxiliary fastening meanscomprising a bent wirecli K resembling an ordinary paper clip. e clip Kcomprises a long loop k extending from the rear edge of the cover, alongthe upper side of the cover, and thence throu h an openin in the tab,and a shorter loop extending rom the rear edge of the cover, along theunder side of vthe cover, and

.thence throu h an opening -in theV tab immediately be ow the cover. Theclip K is placed in osition merely by sliding 1t over the rear e ges ofthe cover, after the tab has extensions of the upper edges of the sidewalls of the cup, forming a continuous flange for preventing the escapeof the contents of the cup, a cover for the cup, anda tab on the cupprojecting through a slot in the cover, the tab having a keystone shapeand the slot having a width less than the maximum width of the tab, toether with auxiliary fastenin means for t e said cover comprising a locing member inserted through ,an opening in the tab and extending alongthe said cover, thereby locking the cover securely in, position.

3. A receptacle com rising a body member, a cover member or the bodymember, one of said members having a slot therein, a. tab extendin fromthe other member through said s ot, and a clip fitting over the edge ofsaid slotted member and extending through the tab on at least one sideof the slotted member.

4. A receptacle com rising a body member, a cover member or the bodymember, one of said members having a slot therein, a tab extending fromthe other member through said slot, and a clip litting over the edge ofsaid slotted member and extending through the tab on both sides of theslotted member.

5. A rece acle comprising-a cup, a sheet cover for t e cup, a keystoneshaped tab projecting from the cup through a slot in the cover, andauxiliary fastening means -for the said-cover comprising a clip littingover the edge of the cover and extending throu h an opening in the tabon at least one si e of the cover.`

6. A receptacle com rising a cup, a sheet cover for the cup, a taprojectin from the cup through a slot in the cover, an auxiliaryfastening means for the said cover comprising a clip fitting over theedge of the cover and extending through an opening in the tab on bothsides of the cover.

7. A receptacle comprising a cup a sheet cover for the cup, a tabprojecting rom the cup through a slot inthe cover, and auxiliaryfastening means for the said cover comprising a clip fitting over theedge ofy the cover angl extending through an opening in the ta 8. Areceptacle comprising a cup, downwardly and inwardly inclined extensionsof the upper edges of the side Walls of the cup,

two of said extensions, on opposite sides of said cup being providedwith notches on their lower free edges, and the extensions of theremaining sides of the cup being provided on their lower free edges withwedge shaped projections, co erating with the said notches, whereby tiesaid extensions are interlocked, to form a continuous flange forpreventing the escape of the contents of the cup.
